The lighthouse in this film is the Angel's Gate at Los Angeles Harbor. It stands at the end of a 1 3/4 mile stone breakwater, and went into service in 1913. It was usually manned by four members of the Coast Guard from then until it was automated in 1973 when a modern searchlight (called an aerobeacon) was installed and the wooden structure surrounding the catwalk was removed. All of the buildings surrounding the lighthouse have also been dismantled. The height of the light is 73 feet (22 m). Its distinctive and unique green light has also been converted to a solar power source. The large fourth-order Fresnel lens of the light seen in this picture has been put on display at the Los Angeles Maritime Museum in San Pedro, California.
An agent was struck by Don Castle's resemblance to a young Clark Gable and took him to MGM, who went on to sign the 20-year-old actor wannabe. He later worked at Paramount but WWII interrupted his career when he was drafted into the Army Air Force. When he returned in 1946, he ended up in this Poverty Row film and in other independent studio pictures.
